[Class 106 (ii)] The work-pieces are placed successively between fixed and sliding anvils, and electrically-operated counters are provided for " correct," " plus " and " minus " dimensions, together with distinctive visual and/or audible indicators, a contact device operated by the sliding anvil being adapted to make and break the circuits 16 of the counters and indicators. A base 1 houses three counters 10, 11, 12 for "correct," " minus and "plus" work-pieces and is fitted with a table 2 for the work. A screwed pillar adjustably supports a housing 5 from which projects an anvil 3 adapted to engage the mark. The anvil is guided in the housing and moves vertically against the influence of a spring 3a. The movements of the anvil 3 are stepped up by a rack 7a and multiplying gearing 9 to give a magnified movement to a sliding bar 8 which is an insulated member carrying a conducting strip 14 from which branch two brush contacts 16, 17. The strip is permanently engaged by a contact 18 connected by a lead 19 through a switch 21 to a source of electricity 20. Normally, the contact 17 is spaced below a fixed contact 11c, and the contact 16 below a fixed contact 10c such that it will engage the fixed contact when the sliding contact 17 leaves the contact 11c. When the contact 16 leaves the contact 10c, it engages a fixed contact 12c. The contacts 10c, 11c, 12c are connected to electromagnets 13 of the counters 10, 11, 12 so that when a work-piece is in position and the switch 21 closed, the appropriate counter will be actuated and at the same time an audible or visible signal 10b, 11b, 12b or both is or are actuated. The length of the fixed contact 10c determines the range of the correct work'-and it may be raised by splitting it diagonally at 22 and moving the segments relatively against a spring 24 by a screw 23. A pointer 6 protruding through a slot in the casing reads over a scale 4a. Each counter may incorporate printing type.

IPC: G01S1/72
Filed: 1920-02-11
Abstract: 138,917. Signal Ges. Nov. 20, 1917, [Convention date]. Locating subaqueous sounds; subaqueous sound signals.-In apparatus for ascertaining the direction of subaqueous sounds, in which two receivers are utilized simultaneously, the natural faculty of the human ears being relied on to estimate direction, each receiver comprises a soundcollecting diaphragm 3 in contact with the water and forming one wall of a coupling-chamber 5 of very small volume communicating through a small orifice 6 with a tube 2 leading to the ear of the observer. Alternatively, the orifice 6 is replaced by a diaphragm, and the coupling-chamber 5 is filled with air under pressure. The diaphragm 3, instead of forming one boundary of the chamber, may be connected therewith by an intermediate member. Two such receivers are mounted on a vessel (e.g. a submarine). The vessel may be swung round until the sound appears to be directly ahead of the observer, or the two receivers may be mounted on a support which is rotated until a like effect is obtained. Alternatively, the lengths of the tubes 2 may be adjustable, the direction of the sound being found from the amount of adjustment necessary to give the " ahead " impression. The distance between the receivers in the water should bear the same ratio to the distance between the ears of the observer as the velocity of sound in water bears to its velocity in air. Specification 147,939 is referred to.
